According to a game modeller that worked on the game who goes under the alias "Zanzibar", the grey-skinned alien guards found in the Tatooine levels were originally meant to be Gamorrean Guards. LucasFilm, however, for reasons unknown, requested that they be changed saying, "Lose the Gamorrean Guards. Make them something else."

The grey-skinned alien guards were designed by LucasArts artist Martin Yee.
